What's the difference between the FR350A and FR350B?
22395
The FR350B is a newer model. Porter Cable no longer supports the FR350A with parts.

the main difference is that one has a hard drive and one has flash storage the 2833 is the faster one of the 2 but most people might not notice the difference

As far as I know there are no other differences. I love my brushless version though, would highly recommend it over the brushed version.

The FR 700 and FR 650 look alike but have different features. I ordered the 700 but received the 650 which is a less expensive unit with less features. No explanation yet from Amazon why this happened. Regardless, it's not good advertising for Amazon.

Performance wise exactly the same. One the 3500 just has HD radio an Xm radio. http://www.crutchfield.com/S-ZndGggohyaX/compare_130X2500BT_130X350BHS/Pioneer-AVH-X2500BT-vs-Pioneer-AVH-X3500BHS.html Chart on crutch-field explaining the differences

The biggest difference is in the porting. The RTR EV1200 is side ported and the F12 is rear ported. I have the RTR because the side porting worked better in my set-up and was the reason I chose it.

It's just the updated model. The red one is newer. No difference though as long as it says that it will read and clear ABS and SRS codes.

Since I have only the 2551, I'm guessing - but it appears the only difference is the color of the face (the area surrounding the vents). Mine is silver and the picture for the 2554 shows a 'gold' or 'bronze' color. Otherwise they seem to be the same fan.

They are fundamentally the same, but R stands for retail. It has a few less features and a shorter warranty. Go for the version without the "R and you will get a 5 year warranty and some more useful control features. I bought 2 of this one, but Amazon has it direct for a little less, but they charge tax in CA. http://www.amazon.com/gp/aag/main/ref=olp_merch_name_9?ie=UTF8&asin;=B00G4CIG7M&isAmazonFulfilled;=1&seller;=A2CHZ585KZGNN0

In the Product Details, the Item model number: EBRCT91MRSB ends in "B". This is technically a "Rear" set. If you find another seller listing the same item model number ending in "A" that is technically a "Front. But having said that, I agree with the general consensus that you can use them interchangeably. Just FYI ... at the time I was writing this, Amazon lists Frequently Bought Together items where the other item frequently bought with this is the model "A" which is the Front set.

If you look at the other model, the FRA052XT7, here on Amazon and scroll down that page, you will find a really nice comparison chart that shows the specifics and details on these two models as well as the five "mini-compact" models Frigidaire offers. Yes, this one does appear to be more energy efficient and other differences are noted there on that product information chart.

As far as I can tell, there is no difference. All of the specs are identical - I thought maybe it was just an "updated" version. Hope this helps!

Dear Pat, The only difference appears to be the base. I have used the FG90 for several years and the base, which appears to be flatter than the FG91, is very stable.

David, I have no idea what the difference is, I never heard of the model 900. After reading the specifications on both and reading the reviews from customers it appears as though the model 900 is a newer version but has exactly the same features. I suppose, based on my research that purchasing the model 900 is probably the better choice.

They're the same. No difference at All.. I ordered the 7518 and receive the 7518xb but was identical.

Just a bit more info... Here's what Motorola Tech Support says:The only difference between the SB5101 and the SB5101U is that the SB5101 has a standby button and the SB5101U does not. Otherwise, they are identical.
